asmielia Posted November 25, 2005 Share Posted November 25, 2005 Hi, I bought 2 sticks of PC4400C25 about 10 months ago or so, and they worked great for a while. I was able to get them up to DDR 590 or so completely stable. As time went on though I started getting some odd behavior in my PC. Random crashes, reboots. I'm pretty sure now that the RAM is defective. It's been a while since I did a memtest run, but basically, the higher I clock the FSB, the more unstable the system gets. Windows runs fine at 275 1:1, which is the RAM's rated speed, but Prime95 fails after 2 mins and there's general system instability. If I drop FSB to 200, Prime95 runs for longer but still fails fairly quickly. Splitting the RAM up and running it in single channel fixes the problem altogether. I've tried 2 sticks of XXXXXXX that I've had for a while, and they don't have any problems clocking up to their rated speed in dual channel, so I don't think it's a motherboard problem. For reference I have an MSI Neo4 Platinum SLI board and an Athlon 3200+ Winchester. Any ideas or is it almost definitely defective? Adrian Link to comment Share on other sites More sharing options...
